Product Description

The BK MUELLER 585-090HC is a Schedule 40 black steel pipe nipple used to create threaded connections in piping systems for gas, water, and general plumbing applications. Manufactured from welded steel with a black finish coating, this nipple measures 1 inch nominal pipe size and 9 inches in length. Threads conform to ASME B1.20.1 and the pipe meets ASTM A733 standards, making it suitable for use in code-compliant commercial and residential installations. Licensed plumbers, pipefitters, and HVAC technicians commonly install this fitting when extending or connecting black iron piping runs.

This nipple is well suited for residential and light commercial piping systems including natural gas supply lines, steam systems, and industrial fluid conveyance. The 1-inch diameter and 9-inch length make it a practical close-to-medium extension fitting for branch lines and equipment connections. It is commonly used wherever black iron pipe is specified by code or system design, including furnace gas supply, boiler piping, and general-purpose threaded pipe assemblies.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), and the International Fuel Gas Code (IFGC) where gas service is involved. Shut off gas or water supply and relieve system pressure before removing or installing any threaded pipe component. Apply an appropriate thread sealant or pipe tape rated for the service type before making up connections. Avoid over-tightening, which can crack fittings or distort threads.
